You Light Up My Life: Developing a Scientific Theory for What Fuels a Candle's Flame!
Young scholars examine how candles work and how scientific theories are developed and tested. Students propose hypotheses about what is burning in a candle then perform tests in order to develop their scientific theory. After a teacher...
Curated OER
The Same But Different
Third graders observe a frozen container filled with ice and discuss what happens when the ice sits out in the room. They practice measuring the mass and volume of the ice, watch as the frozen container is placed in a warm water bath to...
